Ntshiab tungsten

Dab tsi yog Pure Tungsten

Ntshiab tungsten tau siv los ua vuam electrode thaum pib ntawm TIG txheej txheem, rov qab rau xyoo 1940. TIG welding yog tsim los kom muaj txiaj ntsig zoo koom nrog txhuas thiab magnesium alloys, thiab cov ntshiab tungsten ua rau kev txiav txim siab thaum lub sijhawm, vim nws muaj qhov kub siab tshaj plaws ntawm tag nrho cov hlau.

Cov txiaj ntsig ntawm Ntshiab Tungsten

1. Kev tiv thaiv kub kub
Ntawm tag nrho cov hlau nyob rau hauv lawv daim ntawv purest, ntshiab tungsten muaj qhov siab tshaj plaws melting point (3422 degree). Qhov no tuaj yeem muaj txiaj ntsig zoo hauv qee qhov xwm txheej (tshwj xeeb yog thaum piv rau lwm cov hlau ntau dua). Piv txwv li, nws ua kom ntshiab tungsten ib yam khoom zoo heev rau qhov kub thiab txias - qhov no yog vim li cas nws thiaj li siv dav hauv aerospace, tsis siv neeg thiab kev tsim kho kev lag luam.
Tungsten hlau kuj tseem siv tsis tu ncua los tsim cov alloys thiab superalloys. Nws tsis tshua muaj siab melting point thiab tsis kam rau thermal creep pab ntxiv dag zog rau cov hlau, ua rau nws haum rau ntau thermally intensive daim ntaub ntawv, qhov twg lwm yam hlau yuav ua tsis tau tejyam.

2. High-density
Ntshiab tungsten tau txais txiaj ntsig los ntawm qhov ceev heev. Qhov tseeb, ntawm 19.3 g / cm3, nws yog nyob rau hauv qhov siab tshaj plaws ntawm tag nrho cov hlau, nrog tungsten qhov ntom ntsuas kwv yees li ntawm 19.3 npaug ntawm cov dej thiab 1.7 npaug siab dua cov hlau lead.
Raws li qhov tshwm sim ntawm cov cuab yeej no, tungsten tuaj yeem tuav ntau qhov hnyav hauv ib pob me me - thiab feem ntau yog siv rau cov ntawv thov yog qhov xav tau loj me me. Piv txwv li, vim muaj qhov ceev ntawm tungsten, nws yog ib qho kev xaiv zoo heev rau kev sib tw tsheb ballast, aircraft ballast thiab kinetic munitions - uas yuav tsum me me thiab streamlined, tseem muaj peev xwm hloov tau ntau lub zog.

3. Tsawg thermal expansion
Ntshiab tungsten muaj qhov qis tshaj coefficient ntawm thermal expansion ntawm tag nrho cov hlau ntshiab. Piv nrog rau cov khoom tsim khoom (xws li steel), qhov no muab nws cov txiaj ntsig ntawm kev ruaj ntseg ntxiv nyob rau hauv huab cua kub. Nws muaj cov txheej txheem kev sib tw tsis sib xws los ntawm lwm cov hlau thiab tshwj xeeb tshaj yog muaj txiaj ntsig thaum rigidity ntawm qhov kub thiab txias yuav tsum tau - xws li hauv cov cuab yeej ntshiab tungsten carbide txiav los yog dav hlau cav turbine hniav.

4. Cov qauv hluav taws xob
Vim nws cov khoom siv hluav taws xob thiab cov txheeb ze inertness, tungsten hlau yog dav siv hauv kev lag luam hluav taws xob thiab ib puag ncig uas muaj cov hluav taws xob ntau. Vim li no, nrog nws lub ntom ntom heev, tungsten yog ib qho ntawm cov hlau hluav taws xob tiv thaiv kab mob X-zog, cov khoom siv hluav taws xob zoo heev yog qhov nyuaj rau kev xoo hluav taws xob rau nkag mus. Tungsten hlau kuj nquag pom siv hauv electrodes, conductors thiab metallic films.

5. Corrosion-tiv taus
Ntshiab tungsten yog cov resistant rau corrosion thiab yuav siv tau nyob rau hauv ib tug ntau yam ntawm corrosive ib puag ncig thiab sab nraum zoov daim ntaub ntawv. Piv txwv li, nws yog ib qho tseem ceeb tshwj xeeb tshaj yog thaum lub sij hawm raug rau cov khoom corrosive - xws li dej, kua qaub, los yog cov kuab tshuaj - yog qhov zoo.
Ib puag ncig uas feem ntau ntsib corrosive, uas ntau cov hlau tsis tuaj yeem cuam tshuam nrog, yog ib puag ncig marine. Cov dej ntsev, tshwj xeeb, yog cov corrosive heev rau ntau cov hlau. Txawm li cas los xij, thaum alloyed nrog lwm cov hlau, qhov kev tiv thaiv ntawm tungsten hlau ua rau nws tsis tshua muaj neeg tsim nyog rau qhov chaw hnyav, ua rau nws siv tau rau hauv nkoj tsim, nuv ntses lures thiab jewellery.

6. Lub zog hauv kev tsim khoom
Ntshiab tungsten yog cov hlau uas muaj zog heev, nrog lub zog tensile siab tshaj plaws ntawm tag nrho cov hlau ntshiab. Thaum qhov no tuaj yeem ua rau nws nkig nyob rau hauv qee qhov xwm txheej, thaum nws los txog rau cov txheej txheem ntawm kev tsim cov hlau, ntshiab tungsten rigidity txhais tau hais tias nws tuaj yeem kos rau hauv cov xov hlau nyias nyias yam tsis muaj kev tawg.
Tej zaum qhov piv txwv pom tseeb tshaj plaws ntawm qhov no yog kev siv tungsten nyob rau hauv cov ntsiab lus ntawm lub teeb filaments. Hauv daim ntawv thov tshwj xeeb no, cov xov hlau nyias nyias yuav tsum tau ua kom sov rau qhov kub siab heev, txhawm rau kom tawm lub teeb-thiab tungsten lub siab melting point yog qhov tseem ceeb hauv kev tso cai rau qhov no tshwm sim.

Pure Tungsten Chemical Properties

Ntshiab tungsten nyob rau hauv cov pab pawg neeg hloov pauv ntawm chemistry periodic table thiab muaj oxidation xeev ntawm + 2, + 3, + 4, + 5, thiab + 6. Nws muaj tus lej atomic ntawm 74 thiab qhov txheeb ze atomic loj ntawm 183.84. Ntshiab tungsten yog cov khoom nyob rau hauv chav tsev kub vim yog ib qho ruaj khov isometric siv lead ua uas tuaj yeem pom nyob rau hauv x-ray.

Ntshiab tungsten yog heev tiv taus corrosion los ntawm acids thiab tsuas yog yooj yim rau nitric acid thiab hydrofluoric acid. Tsis tas li ntawd, nws tuaj yeem tsis muaj zog los ntawm alkaline oxidizing melts zoo li potassium nitrate lossis sodium hydroxide. Ntshiab tungsten yog heev resistant rau corrosion tab sis yuav ua ke nrog oxygen yooj yim ntawm qhov kub thiab txias heev los tsim trioxides.

Lawm, cov hlau yog sib tov ntawm 5 ruaj khov isotopes xws li tungsten-180, tungsten-182, tungsten-183, tungsten-184, thiab tungsten-186 uas muaj feem pua ntawm 0.12%, 26.5%, 14.3%, 30.6% thiab 28.4% feem.

Ntshiab tungsten lub cev muaj zog

Ntshiab tungsten nyob rau hauv nws daim ntawv purest yog ib tug ci iab dawb hlau uas tau yooj yim ua tiav. Txawm li cas los xij, nws muaj cov pa oxygen thiab carbon nyob rau hauv nws cov tshuaj muaj pes tsawg leeg thiab qhov no ua rau nws nkig heev thaum muab tso rau hauv kev ntxhov siab thiab quab yuam.

Ntshiab tungsten yog qhov hnyav tshaj plaws engineering hlau thiab muaj lub ntom ntom heev (19.25 g / cm³). Qhov no yog vim nws qhov ntom ntom ntom ntom ntom ntom. Nws muaj qhov kub siab heev ntawm 3 140 degree thiab kub kub ntawm 5 700 degree . ntshiab tungsten muaj qhov qis tshaj vapor siab ntawm tag nrho cov hlau thiab muaj lub siab tshaj plaws elasticity modulus ntawm tag nrho cov hlau ntawm 400 GPa.

Nws kuj muaj cov thermal expansion coefficient tsawg heev ntawm 4.4 × 10-6mm degree uas yog hais txog tib yam li cov iav borosilicate thiab qhov no yog vim li cas nws thiaj li siv rau iav hlau seals.Ntshiab tungsten kuj yog ib puag ncig zoo thiab tsis. decompose los yog tawg yooj yim.

Kev tsim cov Pure Tungsten

Ntshiab tungsten yog muab rho tawm thiab purified los ntawm nws cov ore nyob rau hauv ob peb theem. Cov ore yog thaum kawg tig mus rau hauv tungsten (VI) oxide (WO3) uas yog ces rhuab nrog hydrogen los yog carbon roj los tsim ib tug hmoov ntawm tungsten. Lub tungsten tsis tuaj yeem raug molded rau hauv ingots vim tias nws muaj qhov siab melting point thiab melting yog tsis ua lag luam.

Cov hmoov tungsten yog li npaj los ntawm kev sib xyaw nrog me me ntawm npib tsib xee lossis lwm yam hlau zoo nkauj thiab nws yog sintered. Thaum lub sij hawm sintering txheej txheem nickel diffuses thiab tsim ib tug tungsten alloy.
